.To all whom it may concern; Be it known that I, LUOENA M..MoRnE N, a citizen of the United States, of 59 Grand street, Waterbury, county of New, Have'n,; and State of Connecticut, have invented cer tain new and useful Improvements in File- Rings,'fully described and represented in the following specification and the accompanyin drawings, forming a part of the'same.

he purpose of this invention is to furnish joint for the opening section of the soc'alled book-rings having with-the I When'a. laige'zquant ty of heavy papers is";-

In my prior patent No. 808,248 giant d Decern'ber 26, 1905 for book rin with" joint, I have shown a book-ring, liaviiigf parallel side-portionswith -anopening'fijsecai tion hin ed to one ofithe side-portionsfandi having ock-joint with the op osite --side-, portion, such lock-joint having t e engaging. surfaces made concentric with the hinge an formed with ribs having. undercutor dove; tailed edges.

The invention will be understood by reference to the annexed drawing, in which Fig. 1 shows a book-ring with parallel sideportions, with dotted lines showing an alter- L I Specification of Letters Patent; fipgilicationjfile June 1. 1906- Seriallloiiil 67 seigitation of the hingeds' .zm'e n b b 'f having I I "toothepponthe.hinged section?

' ook-rings have been formed with a.joint 7 arranged reversely to mine so that the presconvex su aces, as shown in Fig. 2, any out- Ward pressure of the locking member tends to hold the parts at the joint rigidly in their normal position.

raving thus set forth the nature of the in vention what is claimed herein is:

' 1., The book-ring herein described having :parallel side-portions a and b with integral fleet-portion c' at the bottom, the side portions being relatively longer than the footportion to give them elasticity, the o ening section dat the top jointed to one of t 1e side portions audits point beveledupon the inp r side, the connecting side portion being witnesses.

correspondingly beveled and the opposed beveled faces provided with means for lock-' ing them in engagement, and the overlapping of the section d upon the side portion resisting any outward strain upon such side portion when the book-ring is in use.

2. The book-ring herein described having parallel side portions 0 and b with integral foot-portion c at the bottom, the side or tions being relatively longer than the oot portion to give them elasticity, the o ening section (1 at the top jointed to the si e portion a, and its point beveled upon the inner side and formed with recess f and with transverse tooth e at the end, the side portion I) being correspondingly beveled upon its outer side and ormed with shoulder e and recess f to on age the recess and tooth upon the section the overlapping of the section (1 upon the side portionresisting any outward strain upon such side portion when thebook-ring is in use.

In testimony whereof I have hereunto set my hand in the presence of two subscribing LUCENA M. MORDEN. Witnesses:
